' TRANSMISSION-CLUTCH common To all whom it may concern:

Be it known that 'I, STERLING L. MownRY, a citizen of the United States, residing at Nescopeck, in the county of Luzerne and State of Pennsylvania, have invented certain new and. useful Improvements in Transmission-Clutch Controls, of which the following is a specification, reference being hadto the accompanying drawings. g 1

This invention relates to a transmission gear controlfa'nd has for; its general Ob160t to provide means for locking the gear shifting pedal of a certain type of speed controlling'transmission, in its ow speed ,positlon, bydrawing the brake lever back to a hentrallposition. 7

It is another object of the invention to providelmeans for locking the speed c0ntrolling pedal, from shifting from a neutral position to ahigh speed position, when the emergency brake lever is moved rearward i to apply the brakes V And it is also an important object of the invention to provide a speed control mechanism as f above'icharacterized, the several parts of which'are of very simple form and can be easily and quickly applied in operative position without necessitating any al- I teration in the mounting or arrangement of the controllevers; V Withthe above and other ob e.cts .1 ]'1,V16W

the invention consists in the improved combination, construction and relative arrangement ofthe several partsas will be hercin- 7 after more fully "described, subsequently claimed and illustrated inthe accompanying drawing in which similar reference charac- V ters designate corresponding partsthroughoutthe'several views, andwherein Figure '1 is aside elevation of my im-' proved transmission speed control showing the speed controlling. pedal inits neutralposition and the emergency brake lever'inits g fully released position;

designates thespeed controllingpedal, 6 the brake pedal, and 7 the reverse pedal of a power transimssion control mechanism such as is used on a certain type-of motor vehicles.

The emergency hand brake lever 8 is pro-.

vided with the usual spring pressed locking dog for engagement with a toothed'quadrant 9 suitably secured to the longitudinal'bar 10 of the frame or chassis of'themachine.

Upon the emergency brakeshaft 11, agear. segment 12 is-jadjustablymounted or 'ar ranged, said gear segment havinganfarm provided with a bearing forengagement upon oneside of the shaft 11, a cap plate on half bearing '13 being engaged upon the op-.

posite side ofthe shaft and securely bolted to, said arm, whereby the gear segment is held in its adjusted position. 7 a

7 Upon the inner Side of-tlie frame bar 10, a vertically disposed plate 14 is arranged,

said plate having spaced parallel slot '15 therein and pI'OJGCtlng above andbelowthe frame bar. Attaching plates 16 are'engaged upon the upper and lower sides of the frame bar 10fand are provided with'spaced bolts 17 to extend'through the slots 15 in the plate 314, suitable tightening or clamping 'nuts;18

being threaded upon the ends of said bolts.

Each of the plates 16 at its oppositefend is. formed with'a sleeve'or boss l9'projecting. beyond'the inner side of the frame bar.

These sleeves receive the vertically disposed clamping bolt'20, upon the lower end of which a suitable: clamping nut21 isthreadedh The plate 14 is provided at-it's upper end with an inwardly projecting bearing stud or gudgeon 22. Upon this stud 22, an mice is loosely mounted for turning movement,

said arm having an 'arcuate rack or toothed sector24formed upon one of its ends. This,

toothedsector is' disposed in concentric relation to the bearing stud 22, and the plate .14 is; vertically adjusted to position this bearing stud in coaxial alinement with the op- "eratingshaft, of the sneedcontrollingmechanism upon which the pedal dis s'eouredi 'The major portion of thegarm 23. extends downwardly from the bearing stud 22'," and above said studtheend of the :arm' is .formedwith an ear-25 adapted for engagev ment in the bifurcated end of a member 26,"

which 'forms'anextensionof the 23. r

This end of thef section or member 26' is pivotally or hingedly connectedto the ear must be held in its neutral position or shifted to the position shown in F 1g. 2 by invention is to provide means for locking 4 the pedal 5 in its low speed position, as illus- Inthe operation of the device as above I described,;when it is desired to drive at low 26 has a transverse, pivotal movement upon the upper end of the arm 23. The other end of the member 26 is providedwith an -0pen= ing to receive the bolt 28. Upon one end of this bolt a retaining nut 29 is threaded, while the other end thereof is formed into a yoke 30 for engagement upon the pedal 5.

- In Fig. 1 I have shown the emergency brake lever 8 as thrown to its fully released position and thepedal 5 in neutral positlon.

In this type of transmission gearing the pedal 5 is urged toward its high speed position (not shown) by springs and the pedal trated in Fig. 2,,so thatthe operator need not exert pressure at all times upon this pedal when running at low speed or when the pedal is in neutral.

speed,rthe operator forces the pedal 5 forward, and insuch movement of the pedal,

, the toothed sector 24 is thrown rearward and upward to the position seen in Fig.2

- troll ng pedal; andemergency brake'lever of 100 and simultaneously the hand brake lever is drawn rearward and, the gear segment 12 on the brake shaft is raised and the teeth thereofar'e interlocked with the teeth ofthe sector 24. The lever 8 being lockedfto the quadrant 9,.it will thus be apparent that the pedal is retained orlocked in its low speed position. .iWhen itisde'siredto change the speed to neutral orhigh, the lever 8 is moved :back tothe position shown in 1, thus lowering'the gear segment 12 and releasing the pedal 5 so that it mayflreturn to its neu- Vtral position and. beshifted to its high speed position. In applying the emergencybrakes,

the hand lever, 8 is drawn rearwardly to the position seen in,F,ig. 3.

7 is not operated, and it willtherefore be seen that this movement of the hand lever,

when the gear segment 12 is moved for- ,w iardvand upward it will notengage the teeth of the s amps Fromthe foregolng descr ption, taken in connection with the accompanying drawing,

the'construetion, manner of operation and severaladvantages of my invention will be clearly and fully understood. The device provides a simpleand effective means' for locking the speed controlling -pedalag'ainst movement when dr low speed" but 7 permits the ready release of the pedal when it is desired to change the speed to'high or .The edal; 5 f

WhileI have herein shown and described the preferred construction and arrangement of the several elements, it 1s to be under-' stood that the device is susceptible of c011- siderable modification therein and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit andse'ope of the invention as claimed.
